Certain Variables and Models May. Be Able to Predict Post-ICRS Implantation Outcomes
Investigators conducted a
retrospective chart review of 230 eyes with keratoconus
to identify predictive factors and
develop predictive models for visual acuity changes
following intracorneal ring segment implantation.
Data from one set of eyes were used to explore the correlation between certain
variables and 6-month postoperative changes in uncorrected
and corrected distance visual acuity ( ΔUDVA
and ΔCDVA). The only variable that showed a strong
correlation with ACDVA was preoperative corrected distance visual
acuity; no variables had a strong
correlation with UDVA. The proposed predictive model for AUDVA found
that poorer preoperative UDVA and lower front mean keratometry values led to
greater UDVA gains. PLOS One, February 2024

Only 30 Minutes of Monocular Occlusion May. Be Needed for
Patients with Intermittent Exotropia
In this prospective cohort study,
researchers assessed the optimal duration of monocular
occlusion to eliminate the fusion
effect in patients with intermittent exotropia (N = 40). Deviation angles were
measured both at distance (6 m) and near fixation (0.33 m) before and after 30,
60, and 90 minutes of monocular occlusion. Prior to occlusion, mean deviation
angles were 27.8 PD at distance and 26.0 PD at near fixation. Following
monocular occlusion, mean angles at distance were approximately 32.2, 32.9, and
32.6 PD at 30, 60, and 90 minutes, respectively; at near fixation,
corresponding angles were 37.4, 39.8, and 39.5 PD, respectively. Given these
findings, the authors conclude that 30 minutes of monocular occlusion is enough
time to achieve the maximum deviation angle. Clinical Ophthalmology, January

Good Long-Term Outcomes Are Seen with Epithelial
Transplantations for LSCD
A 15-year retrospective systematic
study compared the long-term outcomes of
cultivated limbal epithelial
transplantation (CLET), simple limbal epithelial transplantation (SLET), and
cultivated oral mucosal epithelial transplantation (COMET) for the treatment of
103 eyes (94 patients) with limbal stem cell deficiency (LSCD). Surgical
success rates were 77.8% for SLET, 57.8% for COMET, and 45.5% for CLET; 7-year
transplantation survival rates were 72.2%, 53.2%, and 50.0%, respectively.
Significant risk factors for surgical failure
were Stevens-Johnson syndrome,
Schirmer I test <5 mm, and the presence of
postoperative recurrent epithelial
defects. The Ocular Surface, April 2024

Benefits and Risks Are Noted with Combined
Topical/Subconjunctival Anesthesia for Phacoemulsification
A double-blind, parallel,
placebo-controlled, randomized trial compared the efficacy of
the combination of topical anesthesia
plus subconjunctival anesthesia vs topical
anesthesia alone for
phacoemulsification. One hundred seventy-six patients aged 240
years with diagnosed senile cataract received
either topical anesthesia with 0.5%
tetracaine hydrochloride plus subconjunctival
injection with 2% lidocaine or topical anesthesia plus placebo. The combination
group exhibited a significantly greater reduction in immediate postoperative
pain than the topical-alone group, with sustained pain reduction over 2 hours.
However, the lidocaine injection itself was reported as painful, and there was
an increased risk of subconjunctival hemorrhage associated with this intervention.

A Thai-Language Version of the Telehealth Usability Questionnaire
Has Early Reliability Data
In this cross-sectional validation
study, investigators developed and assessed a Thai-language version of the
Telehealth Usability Questionnaire (T-TUQ). Two hundred and ten Thai
participants were recruited from 3 specialty clinics: movement disorders, hematology,
and general neurology. The questionnaire was translated from English to create
the T-TUQ version and then underwent back translation and pilot cognitive
interviews. The 5 T-TUQ
scales (ease of use, usefulness,
reliability, effectiveness, and satisfaction) demonstrated good to excellent
internal consistency and high mean usability. The authors conclude that the
T-TUQ may be a reliable and valid instrument for evaluating the usability of
telehealth programs in Thailand. International Journal of Telerehabilitation,

Success of Conjunctivo-Mullerectomy Correlates with Degree
of Ptosis Severity
A prospective cohort study assessed
the efficacy of conjunctivo-mullerectomy in 258 ptotic eyes (159 patients) with
varying ptosis severities (determined by margin-to-reflex difference) as well
as factors that could influence outcomes and complications of this procedure.
At 3 months, surgical success rates for mild, moderate, and severe ptosis were
96.6%, 91.7%, and 83.5%, respectively. Eyes that underwent conjunctivo-mullerectomy
plus tarsectomy had a higher risk of surgical failure than eyes that underwent
conjunctivo- mullerectomy alone. Levator muscle function did not have an impact
on surgical
success or failure. Scientific

Chicago Sky Blue Gel Aids in Identifying and Quantifying
Demodex Mites
In this cross-sectional study, light microscopy
was used on the eyelashes of 30 adults with suspected Demodex blepharitis to
count the number of Demodex mites before and after applying Chicago Sky Blue
(CSB) gel, a new staining product developed to make it easier to see Demodex
mites. Mite counts were assessed by both an untrained and an experienced
investigator. Both the investigators
recorded significantly higher median Demodex mite
counts after the CSB gel was applied.
These findings suggest that CSB gel holds promise
as a diagnostic stain for identifying
and quantifying Demodex mites. Peer, November 2023

A Majority of Patients with Retained IOFBs Have Improved Vision After Treatment
This retrospective cohort study
evaluated risk behaviors and visual outcomes in 161 patients (162
eyes) with retained intraocular foreign bodies (IOFBs)
andexamined the predictive value of the Ocular Trauma Score
(OTS) in determining visual outcomes. Ninety-three percent of
patients were working males. The most common activity
associated with injury was using a grass trimmer or mower. Following
surgical and/or pharmacologic treatment, the percentage of
eyes with vision worse than 20/400 decreased from 78% at baseline
to
34% at the final visit. The OTS showed
high predictive potential for final vision in eyes
in
OTS categories 4 and 5 (better
prognoses). Heliyon, October 2023

In Juvenile Open-Angle Glaucoma, Poor Vision Remains an Issue Even After Treatment
A retrospective multicenter study
assessed the characteristics and treatment outcomes of 104 patients
with juvenile open-angle glaucoma (JOAG). The mean age of JOAG onset was 24
years. Sixty-one percent of patients were male, and 92% of
patients had bilateral disease. Patients were treated with either
antiglaucoma medications or surgery; the most commonly performed surgical
procedure was trabeculectomy with mitomycin-C. In the patients who
underwent trabeculectomy, only 46% achieved
qualified success 10 years after surgery. Regardless of treatment, 15%
of the study population eventually met the World Health
Organization criteria for visual impairment and 21% met the criteria
for blindness. Journal of Glaucoma, November 2023

Primary Angle-Closure Disease Subtypes Have Wide Variations
in 24-Hour IOP Patterns
In a prospective cohort study, 24-hour
IOP patterns were evaluated in 59 eyes of 35 patients with chronic primary
angle-closure disease (PACD). Patients were divided into 3 groups based on type
of PACD: primary angle closure (PAC), primary angle-closure suspect (PACS), and
primary angle-closure glaucoma (PACG). Peak, mean, and trough 24-hour IOP
values and 24-hour IOP fluctuation (difference between peak and trough values)
were compared among groups. Multivariable analysis found that PAC and PACG eyes
showed significantly higher peak IOP and 24-hour IOP fluctuation values than
PACS eyes. When combined PACS and PAC eyes were compared with PACG eyes, PACG
eyes revealed significantly higher 24-hour IOP fluctuation. Journal of

A Fluctuation Index May. Be Able to Predict Responses to
Neovascular AMD Therapy
Using results from the TOWER cohort
study, which assessed the effects of anti-VEGF injections in treatment-naive
patients with neovascular AMD (nAMD) for a period of 1-3 years, the authors
propose a new parameter called the Fluctuation Index (FI) that can be used to
measure retinal fluid fluctuation during nAMD treatment. The FI was based on
the sum of differences (decreased or increased) in 1 mm central subretinal
thickness between each follow-up visit during months 3-24 of TOWER, divided by
the total number of visit intervals. The FI values showed better correlation
with visual outcomes than the traditional standard deviation of foveal thickness/CST.
The presence of intraretinal fluid was predictive
of fluctuating macular thickness over
the time period. Translational Vision Science & Technology, October 2023

Different OCTA Devices Are Not Interchangeable
for Measuring Capillary Density
A prospective study investigated
whether there was agreement among 4 OCT angiography
(OCTA) devices in radial peripapillary capillary (RPC)
density measurements. The study included 48 eyes of 48 participants (19 with glaucoma, 15 with
non-glaucomatous optic neuropathy, and 14 healthy
controls). Each eye was scanned with the OCTA devices in a
random sequence, and grayscale OCTA images from each device were analyzed for RPC density. The
overall interclass correlation coefficient (ICC) was 0.31,
indicating poor correlation among devices. Significant
proportional biases were identified as well. The overall conclusion
was that RPC density obtained from different OCTA devices
varied and thus cannot be used interchangeably; therefore, a
single OCTA device should be used to
monitor optic neuropathy in a specific patient population. Translational Vision Science
