Sivakumar et al
compared the relative effectiveness of methotrexate and mycophenolate
mofetil for noninfectious intermediate uveitis, posterior uveitis, or panuveitis in this multicenter, block - randomized,
observer - masked clinical trial. Eighty patients with noninfectious
intermediate, posterior, or panuveitis
requiring corticosteroid - sparing therapy at Aravind
Eye Hospitals in Madurai and Coimbatore, India were enrolled in this study.
Patients were randomized to receive 25 mg weekly oral methotrexate or 1 g twice
daily oral mycophenolate mofetil and were monitored
monthly for 6 months. Oral prednisone and topical corticosteroids were tapered.
Masked examiners assessed the primary outcome of treatment success, defined by
achieving the following at 5 and 6 months: (1) ≤0.5+ anterior chamber
cells, ≤0.5+ vitreous cells, ≤0.5+ vitreous haze and no active
retinal/choroidal lesions in both eyes, (2) ≤10
mg of prednisone and ≤ 2 drops of prednisolone acetate 1% a day, and (3)
no declaration of treatment failure because of intolerability or safety.
Additional outcomes included time to sustained corticosteroid - sparing control
of inflammation, change in best spectacle - corrected visual acuity, resolution
of macular edema, adverse events, subgroup analysis by anatomic location, and
medication adherence. Forty - one patients were randomized to methotrexate and
39 to mycophenolate mofetil. A total of 67 patients (35 methotrexate, 32 mycophenolate
mofetil) contributed to the primary outcome. Sixty - nine percent of patients
achieved treatment success with methotrexate and 47% with mycophenolate
mofetil (P = 0.09). Treatment failure from adverse events or tolerability was
not different by treatment arm (P = 0.99). There were no differences between
treatment groups in time to corticosteroid - sparing control of inflammation (P
= 0.44), change in best spectacle - corrected visual acuity (P = 0.68), or
resolution of macular edema (P = 0.31).
The authors concluded that there was no statistically significant
difference in corticosteroid - sparing control of inflammation between patients
receiving methotrexate or mycophenolate mofetil.
However, there was a 22% difference in treatment success favoring methotrexate.

Line et al compared the efficacy of topical steroids with topical nonsteroidal anti-inflammatory drugs (NSAIDs) in
controlling inflammation and preventing pseudophakic
cystoid macular edema (PCME) after uncomplicated cataract surgery in patients
undergoing uncomplicated surgery for age - related cataract. The authors
performed a systematic literature search in Medline, CINAHL, Cochrane, and
EMBASE databases to identify randomized trials published from 1996 onward
comparing topical steroids with topical NSAIDs in controlling inflammation and
preventing PCME in patients undergoing phacoemulsification with posterior
chamber intraocular lens implantation for age - related cataract. Postoperative
inflammation and pseudophakic cystoid macular edema
was taken as main outcome measure. Fifteen randomized trials were identified.
Postoperative inflammation was less in patients randomized to NSAIDs. The
prevalence of PCME was significantly higher in the steroid group than in the
NSAID group: 3.8% versus 25.3% of patients, risk ratio 5.35 (95% confidence
interval, 2.94e9.76). There was no statistically significant difference in the
number of adverse events in the 2 treatment groups. The authors found low to
moderate quality of evidence that topical NSAIDs are more effective in
controlling postoperative inflammation after cataract surgery.
They
also concluded that topical NSAIDs are more effective than topical steroids in
preventing PCME and the use of topical NSAIDs was not associated with an
increased events thus recommending using topical NSAIDs to prevent inflammation
and PCME after routine cataract surgery.

Jonathan
et al evaluated cost - effectiveness and cost utilities for treatment options
for vitreomacular adhesions (VMAs) and full - thickness
macular holes (MHs) in this Markov model of cost - effectiveness and utility.
Outcomes of published clinical trials (index studies) of surgical treatment of
VMAs and MHs and a prospective, multicenter clinical trial of pharma-ceutical vitreolysis with intravitreal ocriplasmin with
saline control were used to generate a model for costs of treatment and visual
benefits. All techniques were assumed to result in a 2.5 - line visual benefit
if anatomy was resolved. Markov analysis, with cost data from the Centers for
Medicare and Medicaid Services, was used to calculate imputed costs for each
primary treatment modality in a facility setting, with surgery performed in a
hospital serving as the highest end of the range and nonfacility
setting with surgery performed in an ambulatory surgery center serving as the
lowest end of the range. Imputed costs
of therapy, cost per line saved, cost per line - year saved, cost
per quality - adjusted life years (QALYs) were taken as main outcome measure.
When pars plana vitrectomy (PPV) was selected as the
primary procedure, the overall imputed cost ranged from $5802 to $7931. The
cost per line was $2368 to $3237, the cost per line - year saved was $163 to
$233 and the cost per QALY was $5444 to $7442. If intravitreal
injection of ocriplasmin was the primary procedure,
the overall imputed cost was $8767 to $10 977. The cost per line ranged from
$3549 to $4456, the cost per line - year saved was $245 to $307, and the cost
per QALY was between $8159 and $10 244. If intravitreal
saline injection was used as a primary procedure, the overall imputed cost was
$5828 to $8098. The cost per line was $2374 to $3299, the cost per line - year
saved was $164 to $227, and the cost per QALY was $5458 to $7583. The authors
concluded that is a primary procedure, PPV was the most cost - effective
therapy in this model. The other treatments had similar costs per QALY saved
and compare favorably with costs of therapy for other retinal diseases.

This study was conducted to detect early structural changes of retinal nerve fibre layer (RNFL) and macular ganglion cell complex (GCC)
in subjects with a positive family history for primary open angle glaucoma
(POAG) using Fourier domain optical coherence tomography (FD-OCT) (RTVue-100).
In this cross - sectional observational study First and second degree relatives
of POAG patients, healthy subjects, and subjects with preperimetric
glaucoma (PPG) without a family history for glaucoma, were enrolled. All
participants underwent complete ophthalmic examination, visual field test and
FD-OCT (RTVue-100) imaging. Average RNFL and GCC thicknesses were measured and
a pattern analysis was applied to the GCC map. Analysis of variance (ANOVA),
least significant difference post-hoc test, and multiple ANOVA were used. The
final analysis included 271 eyes divided into several groups: 163 eyes of first
and second degree relatives (85 healthy, 40 with ocular hypertension and 38
with PPG); and 108 eyes of subjects without a positive family history (60
healthy and 48 PPG). RNFL and GCC thickness values of these five groups were
statistically different (p<0.001). RNFL superior, GCC average, GCC superior,
and GCC inferior were found to be significantly thinner and the global loss
volume was higher in normal relatives than in healthy subjects without a
positive family history of POAG (p=0.04, p=0.001, p=0.005, p=0.004, p=0.009).
RNFL and GCC thicknesses obtained by dividing the family members by the degree
of consanguinity showed statistically signifi-cant
thinning in siblings of glaucomatous subjects than in offspring. The authors concluded that the eyes of
subjects with a positive family history for POAG have significantly thinner
RNFL and GCC than normal eyes and a more accurate follow-up has to be performed.
