RESUMO
Aim: To review the efficacy and safety of two common postoperative regimens following Kahook Dual Blade goniotomy with phacoemulsification cataract extraction (KDB-CE). Materials and methods: This is a retrospective review of eyes undergoing KDB-CE from May 2016 to 2018 by a single surgeon. Almost 12-month follow-up data were assessed for two common postop regimens-treatment with (1) topical prednisolone acetate 1% with pilocarpine 1% (pred-pilo) or (2) difluprednate 0.05% postoperatively. Postoperative results were compared to each respective baseline intraocular pressure (IOP) levels. Results: There were 53 eyes in the difluprednate group and 25 eyes in the pred-pilo group. In the difluprednate group, the IOP decreased at postoperative day 1 (POD1) [16 ± 5 baseline vs 15 ± 5 POD1, mean ± standard deviation (SD) in mm Hg, and p = 0.321], but increased at postoperative week 1 (POW1) due to a 15% rate of IOP-spikes (19 ± 9, p = 0.099). The number of IOP-lowering drops decreased from baseline (2 ± 1 drops) to 1 ± 1 drops at POD1 (p < 0.0001), and remained at 1 ± 1 drops through postoperative month 12 (POM12) (p < 0.0001). In the pred-pilo group, there was a statistically significant decrease in mean IOP at POW1 (16 ± 4 POW1 vs 18 ± 6 baseline, p = 0.044), which persisted through POM6. The number of IOP-lowering drops was not statistically significantly lower from baseline at POM3 (2 ± 1 at POM3, p = 0.188). Spikes in IOP, corneal edema, and hyphema were the most common complications. Conclusion: Both postoperative regimens were effective following KDB-CE at reducing IOP at 12 months. The difluprednate group was likely to experience an IOP-spike at POW1 but used fewer IOP-lowering drops 12 months after KDB goniotomy. In the pred-pilo group, the number of IOP-lowering drops was equivalent to baseline levels at POM3. Aside from IOP spikes, there were similar complication rates observed between the two postoperative regimens. Due to demographic differences, it was not possible to compare relative IOP-lowering efficacy between the two postoperative regimens. Clinical significance: It is efficacious and safe to use either postoperative regimen following KBD-CE. Postoperative trajectories may differ with respect to the postoperative regimen, but further randomized controlled trials are needed to compare various topical steroid medications for postoperative regimens following KDB-CE.

RESUMO
PURPOSE: To compare the 18-month efficacy and safety of Kahook Dual Blade goniotomy (KDB) in combination with cataract surgery (combined group) or as a standalone procedure (standalone group). SETTING: Single surgeon practice. DESIGN: Retrospective review study. METHODS: A total of 116 eyes of 100 patients underwent KDB by a single well-experienced surgeon from May 2016 to 2018. A total of 93 eyes and 23 eyes were in the combined and standalone groups, respectively. Main outcome measures were reduction in intraocular pressure (IOP) and IOP-lowering medication and adverse events. Data were collected and analyzed using Welch t tests in R. RESULTS: A total of 116 eyes of 100 patients were included in the analysis. Moderate or severe glaucoma was observed in 71% of eyes in the combined group compared with 83% in the standalone group. At baseline, mean IOP was 16.5 ± 5.0 mm Hg (n = 93) and 24.3 ± 9.1 mm Hg (n = 23) in the combined and standalone groups, respectively (P < .05). The IOP decreased in both groups at 12 months (14.1 ± 3.9 vs 16.9 ± 7.6, P = .24) and 18 months (14.4 ± 3.7 vs 16.7 ± 7.6, P = .5). There was a statistically significant difference in the number of drops between the combined and standalone groups at baseline (2.4 ± 1.2 vs 2.9 ± 1.0, P < .05) persisting at 12 months (1.3 ± 1.2 vs 2.6 ± 1.2, P < .05) and at 18 months (1.3 ± 1.2 vs 3.3 ± 1.2, P < .05). Complications included transient hyphemas (20 eyes [17%]) and IOP spike (20 eyes [17%]). Seven eyes required additional glaucoma surgery, 5 of which were in the standalone group. CONCLUSIONS: KDB was an effective and safe procedure for different glaucoma disease severities, whether combined with cataract surgery or as a standalone surgery. It is an alternative to consider prior to pursuing more invasive glaucoma surgeries.

PURPOSE: To compare the diagnostic performance of human gradings vs predictions provided by a machine-to-machine (M2M) deep learning (DL) algorithm trained to quantify retinal nerve fiber layer (RNFL) damage on fundus photographs. DESIGN: Evaluation of a machine learning algorithm. METHODS: An M2M DL algorithm trained with RNFL thickness parameters from spectral-domain optical coherence tomography was applied to a subset of 490 fundus photos of 490 eyes of 370 subjects graded by 2 glaucoma specialists for the probability of glaucomatous optical neuropathy (GON), and estimates of cup-to-disc (C/D) ratios. Spearman correlations with standard automated perimetry (SAP) global indices were compared between the human gradings vs the M2M DL-predicted RNFL thickness values. The area under the receiver operating characteristic curves (AUC) and partial AUC for the region of clinically meaningful specificity (85%-100%) were used to compare the ability of each output to discriminate eyes with repeatable glaucomatous SAP defects vs eyes with normal fields. RESULTS: The M2M DL-predicted RNFL thickness had a significantly stronger absolute correlation with SAP mean deviation (rho=0.54) than the probability of GON given by human graders (rho=0.48; P < .001). The partial AUC for the M2M DL algorithm was significantly higher than that for the probability of GON by human graders (partial AUC = 0.529 vs 0.411, respectively; P = .016). CONCLUSION: An M2M DL algorithm performed as well as, if not better than, human graders at detecting eyes with repeatable glaucomatous visual field loss. This DL algorithm could potentially replace human graders in population screening efforts for glaucoma.

Retained cranial blade injuries are uncommon events lacking standardized recommendations for appropriate surgical extraction. The authors present a case of a 30-year-old male who sustained a penetrating blade injury of the left orbit with intracranial extension through the skull base into the temporal lobe. The patient walked to the emergency room and remained alert. Clinically, the patient had only a small laceration of the left upper eyelid with no gross visual impairment.The radiological investigation confirmed the presence of a knife blade in the orbit. Intraoperative management included an intracranial approach and an extracranial craniofacial dissection for blade visualization and soft tissue protection, globe protection and to avoid any major bleeding. A thorough review of the penetrating cranial injuries literature is presented and a trauma management algorithm is offered for the care of similar injuries.

PURPOSE: To report the occurrence and management of severe infectious scleritis in a 75 year-old woman following intravitreal ranibizumab injection. OBSERVATIONS: A 75 year-old monocular woman receiving monthly intravitreal ranibizumab injection for wet age related macular degeneration in the left eye presented with severe dull pain, decreased vision, and scleral melt with discharge 2 weeks after her last injection. The dilated fundus exam was devoid of vitritis. The patient was admitted to our hospital for both diagnostic and therapeutic purposes. She was initially started on aggressive oral and topical antibiotics, but showed no significant improvement. The scleral cultures were positive for Pseudomonas aeruginosa. In view of the aggressive nature of her infection, intravenous antibiotics were added to the treatment regimen. The patient recovered her baseline visual function after two weeks of intravenous, oral and, topical antibiotics. CONCLUSIONS AND IMPORTANCE: To our knowledge, this is the first case of anterior infectious necrotizing scleritis secondary to Pseudomonas aeruginosa infection following intravitreal ranibizumab injection. Clinicians performing intravitreal injections should have a high index of suspicion for iatrogenic infections including scleritis and endophthalmitis, as these infections require aggressive topical and systemic antibiotics as well as possible hospitalization.
RESUMO
BACKGROUND: We conducted a systematic review to examine the efficacy of the Atkins, South Beach, Weight Watchers (WW), and Zone diets, with a particular focus on sustained weight loss at ≥12 months. METHODS AND RESULTS: We systematically searched MEDLINE, EMBASE, and the Cochrane Library of Clinical Trials to identify randomized controlled trials (RCTs) published in English with follow-up ≥4 weeks that examined the effects of these 4 popular diets on weight loss and cardiovascular risk factors. We identified 12 RCTs (n=2559) with follow-up ≥12 months: 10 versus usual care (5 Atkins, 4 WW, and 1 South Beach) and 2 head-to-head (1 of Atkins, WW, and Zone, and 1 of Atkins, Zone, and control). At 12 months, the 10 RCTs comparing popular diets to usual care revealed that only WW was consistently more efficacious at reducing weight (range of mean changes: -3.5 to -6.0 kg versus -0.8 to -5.4 kg; P<0.05 for 3/4 RCTs). However, the 2 head-to-head RCTs suggest that Atkins (range: -2.1 to -4.7 kg), WW (-3.0 kg), Zone (-1.6 to -3.2 kg), and control (-2.2 kg) all achieved modest long-term weight loss. Twenty-four-month data suggest that weight lost with Atkins or WW is partially regained over time. CONCLUSIONS: Head-to-head RCTs, providing the most robust evidence available, demonstrated that Atkins, WW, and Zone achieved modest and similar long-term weight loss. Despite millions of dollars spent on popular commercial diets, data are conflicting and insufficient to identify one popular diet as being more beneficial than the others.

The objective of this study was to present a unique case of unilateral facial nerve palsy as an isolated complication of herpes zoster ophthalmicus. An 82-year-old immunocompetent male presented with a 1-week history of painful left scalp lesions. The diagnosis of left herpes zoster ophthalmicus with associated keratoconjunctivitis was established. A 7-day course of oral acyclovir (800 mg/day) along with topical prednisolone acetate 1% and moxifloxacin were started. Three weeks later, the ocular zoster involvement resolved and the vesicular lesions of the skin had regressed. However, the patient developed an isolated left Bell's palsy that gradually improved with conservative therapy. To the best of our knowledge, we present an unusual case of herpes zoster ophthalmicus complicated by an isolated ipsilateral Bell's palsy. The patient has had a near complete resolution of all symptoms after antiviral therapy for the zoster ophthalmicus component along with conservative management for the Bell's palsy.
