RESUMO
TOPIC: This systematic review and meta-analysis investigates the efficacy and safety of anti-vascular endothelial growth factor (anti-VEGF) injections compared to surgical intervention in improving visual acuity (VA) and reducing complications for patients with submacular hemorrhage (SMH) due to neovascular age-related macular degeneration (AMD). CLINICAL RELEVANCE: Determining the optimal intervention for SMH in AMD is crucial for patient care. METHODS: We included studies on anti-VEGF injections or surgical interventions for SMH in AMD from 7 databases, searched up to May 2024. Data extraction and quality assessment were done by two independent reviewers. Certainty of evidence was assessed GRADE approach. Meta-analysis employed random-effects models. Primary outcomes were pooled mean logMAR VA difference (initial examination minus last follow-up VA) and adverse events rates. RESULTS: A total of 43 observational studies were included: 21 (960 eyes) on anti-VEGF and 22 (455 eyes) on surgery. Comparisons were made across separate studies due to lack of head-to-head studies. Meta-analysis included 11 anti-VEGF studies (444 eyes) and 12 surgical studies (195 eyes) for VA outcomes. The mean difference (MD) in VA was -0.16 (95%CI: -0.26,-0.07) for anti-VEGF and -0.36 (95%CI: -0.68,-0.04) for surgery, with no significant difference between groups (X2=1.70, df =1, p=0.19). Heterogeneity was high in surgical studies (I2=96.2%, tau2=0.23, p<0.01) and negligible in anti-VEGF studies (I2=7%, tau2=0.003, p=0.38). GRADE certainty was moderate for anti-VEGF and low for surgery. Anti-VEGF had lower rates of cataract (0% vs 4.6%), proliferative vitreoretinopathy (PVR, 0.1% vs 2.0%), and retinal detachment (RD, 0.1% vs 10.6%), but similar rates of recurrent hemorrhage (5.4% vs 5.3%). Complications were summarized descriptively due to zero cell problem. CONCLUSION: Both anti-VEGF and surgery treat SMH in AMD with similar VA outcomes but different safety profiles. Anti-VEGF is preferred for less severe hemorrhage, while surgery is suited for extensive hemorrhage. Despite uncertain comparative VA outcomes, treatment should be guided by clinical judgment and patient factors.
RESUMO
PURPOSE: To compare the refractive accuracy of legacy and new no-history formulas in eyes with previous myopic laser vision correction (M-LVC). DESIGN: Retrospective cohort study. METHODS: Setting: Two academic centers Study Population: 576 eyes (400 patients) with previous M-LVC that underwent cataract surgery between 2019-2023. A SS-OCT biometer was used to obtain biometric measurements, including standard (K), posterior (PK), and total keratometry values (TK). OBSERVATION PROCEDURES: Refractive prediction errors were calculated for 11 no-history formulas: two legacy M-LVC formulas, four new M-LVC formulas using K values only, and five new M-LVC formulas using K with PK or TK. MAIN OUTCOME MEASURES: Heteroscedastic testing was used to evaluate relative formula performance, and formulas were ranked by root mean square error (RMSE). RESULTS: New M-LVC formulas performed better than legacy M-LVC formulas. New M-LVC formulas with PK/TK values performed better than versions without PK/TK values. Among new M-LVC formulas with PK/TK values, EVO 2.0-PK was superior to Hoffer QST-PK (P < 0.005). Among new M-LVC formulas using K only, Pearl DGS-K and EVO 2.0-K were both superior to Hoffer QST-K and Barrett True K NH-K formulas (all P < 0.005). CONCLUSIONS: Surgeons should favor using new no-history post M-LVC formulas over legacy post M-LVC formulas whenever possible. The top-performing M-LVC formulas (EVO 2.0-PK, Pearl DGS-PK, and Barrett True K-TK) utilized posterior corneal power values. Among formulas utilizing K alone, the EVO 2.0-K and Pearl DGS-K performed best.

Background/Aims: Neurotrophic keratitis (NK) is a neurodegenerative disease that can lead to corneal hypoesthesia, decreased tear production, and epitheliopathy. Based on the severity of ocular surface damage, NK is classified into 3 stages. Stage 1 NK is characterized by superficial punctate keratopathy, tear film instability, and reduced corneal sensation. The therapeutic efficacy of PRGF eye drops for NK stages 2 and 3 has been previously reported. In this study, we evaluated the efficacy and safety of autologous PRGF eye drops in improving corneal sensitivity and other ocular surface clinical signs in patients with stage 1 NK. Methods: Retrospective chart review. Results: 26 eyes of 15 stage 1 NK patients (seven males, eight females), aged 76.3 ± 12.1 years, were included in the study. The mean treatment duration was 2 ± 1.8 months. With PRGF treatment, corneal sensitivity increased from 2.8 to 4.5 cm in 53.8% (14/26) (p < 0.01), TBUT increased from 3.6 to 5.0 s in 69.2% (18/26) (p < 0.01), and Schirmer score increased from 13.7 to 16.8 mm in 80.7% (21/26) of treated eyes (p < 0.01). Similarly, an improvement in corneal staining (punctate epithelial erosions) and MMP-9 levels was seen in 80.7% (n = 21) and 65.4% (n = 17) of treated eyes, respectively. BCVA improvement was seen in 26.9% of treated eyes (n = 7). Conclusions: This study demonstrates the effective role of PRGF therapy in recovering corneal sensation and tear film function and in the healing of corneal erosions in stage 1 NK patients.
RESUMO
Objectives: To analyze corneal sensitivity with a new noncontact and hand-held esthesiometer (Brill Engines, Spain) in patients with dry eye disease (DED) and patients on hypotensive drops, and to compare it with healthy subjects. Methods: 31 patients (57 eyes) with DED, 23 patients (46 eyes) with glaucoma and 21 healthy patients (33 eyes) were recruited. In all patients, corneal sensitivity was measured. Subsequently, a keratography test (Keratograph 5M, Oculus) was carried out to measure tear meniscus height (TMH), non-invasive break up time (NIBUT), bulbar redness (Jenvis scale) and corneal staining (CS, Oxford scale). Both corneal sensitivity and ocular surface parameters were compared between DED, glaucoma, and healthy subjects. Linear mixed models were constructed to utilize data from both eyes of patients. A 95% confidence level was considered statistically significant. Results: The mean age was 56.1±16.1 years in DED group, 69.5±11.7 years in the glaucoma group and 36.3±10.5 years in the control group. Adjusting for age and sex, esthesiometry was significantly worse in DED and glaucoma vs control group (p = 0.02 and p = 0.009, respectively). NIBUT was lower in DED and glaucoma patients (p < 0.001 and p = 0.001, respectively). Redness and CS values were higher in DED group (p = 0.04 and p = 0.001, respectively). TMH was lower in the glaucoma patients (p = 0.03). Conclusions: Corneal sensitivity measured with a novel noncontact esthesiometer was reduced in DED and glaucoma patients compared to controls. In clinical practice, this esthesiometer could be an easy-to-use device to evaluate for patients with subclinical neurotrophic keratopathy.
