RESUMO
TOPIC: Topical Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) for Management of Pain in Patients After Photorefractive Keratectomy (PRK). CLINICAL RELEVANCE: Pain after PRK is a major concern for both patients and surgeons. While evidence supports the use of NSAIDs postoperatively, no consensus exists regarding the preferred regimen. The study aimed to compare the efficacy and safety of different topical NSAIDS. METHODS: The study was prospectively registered with PROSPERO (ID -CRD42023417651). A systematic search of electronic databases was done, for randomized control trials (RCTs) reporting topical NSAIDs' outcomes of corneal reepithelization, rescue analgesics intake, and pain in days 0-3 after PRK (POD0-3). Studies were graded for risk of bias. Data were extracted and Standardized Mean Differences (SMDs) were evaluated in a network meta-analysis in accordance with the Cochrane's guidelines, to which frequentist approach model was fitted. Transitivity was assessed using the net-split method. Treatment effectiveness was ranked using forest plots based on comparison to placebo. P-scores (P) and league tables were used to examine combined direct and indirect comparisons. RESULTS: Out of 1540 studies identified, 27 were included. These encompassed 2286 patients across 11 countries, evaluating 7 distinct topical NSAIDs. At POD0 ketorolac (P 0.764), flurbiprofen (P 0.763), and bromfenac (P 0.717) were the most efficient drugs overall and displayed significantly lower pain scores than placebo. Other than that, flurbiprofen held the highest rank for reported pain throughout, significantly outperforming placebo on POD1 (P 0.874, SMD -1.19, 95%CI [-1.86, -0.52]), POD2 (P 0.882, SMD -1.05, 95%CI [-1.82, -0.27]), and POD3 (P 0.939, SMD -1.14, 95%CI [-2.1, -0.18]). Other NSAIDs were significantly better than placebo only on POD1 and POD0. Rescue analgesic intake analysis favored indomethacin (P 0.834, SMD -0.8, 95%CI [-1.33, -0.27]), ketorolac, and diclofenac. Compared to placebo, reepithelization was slowed to different significances with all NSAIDs but flurbiprofen (P 0.991, SMD -0.7, 95%CI [-1.38, -0.03]). CONCLUSIONS: Flurbiprofen was favorable in pain scores on typically postoperative painful days and reepithelization times. However, analgesics intake, a more objective outcome, suggested superiority of other NSAIDs. Inconsistencies may be explained by the small sample size. For clinical interpretation, NSAIDs effect sizes should be taken into consideration.
RESUMO
BACKGROUND: To report a case of unusual presentation of retinochoroiditis caused by Rickettsia typhi in a patient without prior uveitis. CASE PRESENTATION: In this case, we describe a 24-year-old male soldier with no previous eye disease, who was referred to our ophthalmology department due to bilateral retinochoroiditis and vitritis. The patient initially presented with a paracentral scotoma in his right eye persisting for 7 days and scattered dark spots in his left eye for 2 days in June 2023. Preceding these ocular symptoms, he experienced a two-week episode of fever, headaches, night sweats, and rapid weight loss of 10 kg. A transient rash covered his body briefly. His mother had a history of recurrent eye inflammation. Physical examination revealed bilateral keratic precipitates on the lower corneal periphery, 1 + anterior vitreous cells, small retinal lesions and mild optic discs elevation. Fluorescein angiography indicated mild discs hyperfluorescence, and the clinically visible round punctate lesions on OCT showed inner retinal hyper-reflective lesion with a depth till outer plexiform layer possibly suggestive of a retinitis lesion. Laboratory tests were normal except thrombocytosis, elevated ESR, liver enzymes and ACE levels, with positive Rickettsia typhi serology tests. Rheumatology and infectious disease consultations ruled out autoimmune diseases, confirming Rickettsia typhi infection. Treatment included systemic doxycycline and prednisone, with improvement of visual acuity, ocular symptoms, OCT abnormalities and resolution of inflammation. Prednisone was discontinued, and after two months, additional improvement was seen clinically, with preserved retinal structures on OCT. CONCLUSION: This study explores retinochoroiditis as a rare ocular presentation of Rickettsia typhi, an unusual infection in the Middle East. Previously reported ocular manifestations include conjunctivitis, vitritis, post infectious optic neuropathy and a few cases of uveitis. Ocular symptoms followed systemic illness, highlighting the need for awareness among clinicians. Diagnosis relies on seroconversion, with fluorescein angiography and OCT aiding in assessment. Empiric doxycycline and systemic corticosteroid therapy is recommended. Ocular symptoms resolved in two months. Awareness of these ocular manifestations is essential for timely diagnosis and management. Further research is needed to fully understand this aspect of murine typhus.

INTRODUCTION: Artificial intelligence (AI) was first introduced in 1956, and effectively represents the fourth industrial revolution in human history. Over time, this medium has evolved to be the preferred method of medical imagery interpretation. Today, the implementation of AI in the medical field as a whole, and the ophthalmological field in particular, is diverse and includes diagnose, follow-up and monitoring of the progression of ocular diseases. For example, AI algorithms can identify ectasia, and pre-clinical signs of keratoconus, using images and information computed from various corneal maps. Machine learning (ML) is a specific technique for implementing AI. It is defined as a series of automated methods that identify patterns and templates in data and leverage these to perform predictions on new data. This technology was first applied in the 1980s. Deep learning is an advanced form of ML inspired by and designed to imitate the human brain process, constructed of layers, each responsible for identifying patterns, thereby successfully modeling complex scenarios. The significant advantage of ML in medicine is in its' ability to monitor and follow patients with efficiency at a low cost. Deep learning is utilized to monitor ocular diseases such as diabetic retinopathy, age-related macular degeneration, glaucoma, cataract, and retinopathy of prematurity. These conditions, as well as others, require frequent follow-up in order to track changes over time. Though computer technology is important for identifying and grading various ocular diseases, it still necessitates additional clinical validation and does not entirely replace human diagnostic skill.

PURPOSE: To identify factors associated with changes in the posterior corneal curvature following laser-assisted in situ keratomileusis (LASIK). METHODS: This retrospective study included myopic astigmatic eyes that underwent LASIK between January and December 2013 at Care-Vision Laser Center, Tel-Aviv, Israel. The average posterior keratometry was measured with the Sirius device at a radius of 3 mm from the center. The correlations between the surgically induced change in average posterior keratometry and preoperative parameters such as preoperative sphere, cylinder, spherical equivalent, central corneal thickness (CCT), refraction, Baiocchi Calossi Versaci (BCV) index, ablation depth, percent of tissue altered (PTA), and residual stromal bed (RSB) are reported. RESULTS: A total of 115 eyes with a mean age of 32.5 ± 8.3 years (range 22-56 years) were included. Central corneal thickness (p < 0.005), preoperative sphere (p < 0.001), spherical equivalent (p < 0.005), and preoperative posterior inferior/superior ratio (p < 0.05) were all significantly correlated with the percentage of change in the mean posterior K. According to ranked stepwise multiple regression analysis, 22% of the variance of change in posterior K could be explained by the examined factors. The factors that remained significant were the percentage of change in posterior inferior/superior ratio, preoperative subjective sphere, and preoperative mean posterior K (for all, p < 0.001). CONCLUSIONS: The percentage of change in posterior inferior/superior ratio, subjective sphere, and preoperative mean posterior K are all correlated with change in the mean posterior K after LASIK. Understanding of the variables that can influence posterior corneal changes following refractive surgery may play a role in the prevention of iatrogenic keratectasia.

PURPOSE: To review the efficacy and safety of oral doxycycline antibiotics versus macrolides in the treatment of meibomian gland dysfunction (MGD). DESIGN: Systematic review and meta-analysis. METHODS: We performed a systematic search of electronic databases for all peer-reviewed published studies which included clinical outcomes of oral antibiotic MGD treatment. Individual study data were extracted and evaluated in a weighted pooled analysis, including total sign and symptom scores, meibomian gland secretion score, tear break-up time (TBUT), fluorescein staining score and rate of complications. RESULTS: Two thousand nine hundred and thirty-three studies were found, of which 54 were eligible for the systematic review, and six prospective studies were ultimately included for analysis, reporting on 563 cases from three countries. Age of affected patients ranged between 12 and 90 years. Overall, both treatment methods induced improvement in MGD signs and symptoms. In pooled analysis, macrolides were significantly superior in the total signs score (pooled standardized mean difference (SMD) -0.51, 95% confidence interval (CI): -0.99 to -0.03), meibomian gland secretion score (pooled SMD -0.25, 95%CI: [-0.48, -0.03]), TBUT (SMD -0.31, 95%CI: [-0.50, -0.13]) and fluorescein staining score (SMD -1.01, 95%CI: [-1.72, -0.29]). Moreover, while no severe complications were reported for both treatments, the macrolide group exhibited significantly less adverse events (pooled odds ratio 0.24 with a 95% CI of 0.16 to 0.34). CONCLUSIONS: Both macrolides and tetracyclines are effective treatments for MGD. In this study, macrolides exhibited better efficacy and safety profile compared to tetracyclines.

Objectives: To assess the decrease in myopia progression and rebound effect using topical low-dose atropine compared to a combined treatment with contact lenses for myopic control. Methods: This retrospective review study included 85 children aged 10.34 ± 2.27 (range 6 to 15.5) who were followed over three years. All had a minimum myopia increase of 1.00 D the year prior to treatment. The children were divided into two treatment groups and a control group. One treatment group included 29 children with an average prescription of 4.81 ± 2.12 D (sphere equivalent (SE) range of 1.25−10.87 D), treated with 0.01% atropine for two years (A0.01%). The second group included 26 children with an average prescription of 4.14 ± 1.35 D (SE range of 1.625−6.00 D), treated with MiSight 1 day dual focus contact lenses (DFCL) and 0.01% atropine (A0.01% + DFCL) for two years. The control group included 30 children wearing single-vision spectacles (SV), averaging −5.06 ± 1.77 D (SE) range 2.37−8.87 D). Results: There was an increase in the SE myopia progression in the SV group of 1.19 ± 0.43 D, 1.25 ± 0.52 D, and 1.13 ± 0.36 D in the first, second, and third years, respectively. Myopia progression in the A0.01% group was 0.44 ± 0.21 D (p < 0.01) and 0.51 ± 0.39 D (p < 0.01) in the first and second years, respectively. In the A0.01% + DFCL group, myopia progression was 0.35 ± 0.26 D and 0.44 ± 0.40 D in the first and second years, respectively (p < 0.01). Half a year after the cessation of the atropine treatment, myopia progression (rebound effect) was measured at −0.241 ± 0.35 D and −0.178 ± 0.34 D in the A0.01% and A0.01% + DFCL groups, respectively. Conclusions: Monotherapy low-dose atropine, combined with peripheral blur contact lenses, was clinically effective in decreasing myopia progression. A low rebound effect was found after the therapy cessation. In this retrospective study, combination therapy did not present an advantage over monotherapy.
