RESUMO

INTRODUCTION: This retrospective study explores the connection between preoperative patient risk factors, the experience of ophthalmology residents, and the outcomes of cataract surgeries performed at Hadassah Medical Center. It is hypothesized that with increased experience, residents may demonstrate greater proficiency in handling surgeries on higher-risk patients, potentially leading to improved surgical outcomes overall. METHODS: Data were examined from 691 consecutive cataract surgeries in 590 patients, conducted by ophthalmology residents at Hadassah Medical Center (January 2018 to February 2022). Demographics, surgeon experience, preoperative cataract risk assessment score, and pre- and postoperative corrected distance visual acuity (CDVA) were analyzed. The risk score was based on cataract density, previous vitrectomy, presence of phacodonesis, small pupil, extreme axial length (> 30 mm or < 21.5 mm) or abnormal axial length (26-30 mm), shallow anterior chamber (< 2.5 mm), poor patient cooperation, oral alpha-1 blocker use, diabetic retinopathy (DR), Fuchs endothelial dystrophy, and having one functioning eye. This study focused on the correlation of risk scores with residents' surgical experience and surgical outcomes. RESULTS: As residents gained experience, surgeries on patients with at least one risk factor increased from 54% (first year) to 75% (second year; p < 0.001) and fluctuated between 75%, 82%, and 77% (third, fourth, and fifth years, respectively), with initial preoperative CDVA declining progressively. Despite handling more complex cases over time, the percentage of intraoperative complications per patient decreased with each year of residents' experience (17%, 13%, 11%, 17%, 6%; respectively). Patients without any risk factor had higher postoperative CDVA than those with one or more risk factors (mean ± standard deviation [SD] in logMAR, 0.16 ± 0.26 vs. 0.27 ± 0.35; p < 0.001) and a higher percentage of CDVA improvement (63% vs. 57%, p = 0.016). CONCLUSIONS: The use of a preoperative risk assessment scoring system to allocate surgeries to residents at varying experience levels may reduce the risk for surgical complications, thereby ensuring patient safety and providing residents with a gradual learning experience.

RESUMO

We report the long-term follow-up of an immunocompetent patient who presented with slowly progressive endogenous endophthalmitis secondary to Streptococcus anginosus. A 46-year-old healthy man presented with a two-month history of right eye iritis. On examination, visual acuity was 20/60 with intraocular pressure of 6 mm Hg. There was a small layer of hypopyon with non-granulomatous anterior uveitis and vitritis. On funduscopy, fluffy white peripheral retinal and pre-retinal lesions were noted in superonasal periphery. The patient denied any present or past illness. Diagnostic pars plana vitrectomy was performed. Culture and polymerase chain reaction of the vitreous sample were positive for Streptococcus anginosus. Intravitreal vancomycin and ceftazidime and systemic ceftriaxone were administered. Work-up which included blood and urine cultures, chest x-ray, echocardiography and abdominal ultrasound was unyielding. Subsequently and because of persistent post-infectious inflammatory reaction, intravitreal and oral steroids were administered in addition to oral azathioprine later on. After one year of follow-up, visual acuity was 20/20 with near vision of Jaeger 3 + and no signs of active uveitis were seen. Therefore, Streptococcus anginosus should be considered in the differential diagnosis of a slowly progressive endophthalmitis also in immunocompetent individuals.

RESUMO

Premacular membranes developing following pars plana vitrectomy (PPV) can cause significant anatomical and functional deficits to the macula. Recent reports showed that postoperative premacular membranes are a localized presentation of macular proliferative vitreoretinopathy (mPVR). Here, we report retrospectively a case series of 5 patients with severe mPVR which developed following uneventful PPV and were followed up to 32 months in the Department of Ophthalmology, Hadassah-Hebrew University Medical Center, Jerusalem, between October 2016 and February 2020. All patients underwent primary repair of rhegmatogenous retinal detachment (RRD) before mPVR developed. Mean best-corrected visual acuity (BCVA) at presentation was 20/76 Snellen (0.58 LogMAR). Median duration of the retinal detachment time until surgery was 1.5 days (range 1-21 days). Mean interval time from last normal follow-up exam to diagnosis of mPVR was 19 days (range 10-28). BCVA dropped from a mean of 20/38 Snellen (0.28 LogMAR) prior to mPVR development to 20/166 Snellen (0.92 LogMAR) following its development, recovering to 20/57 Snellen (0.45 LogMAR) after peeling of membranes. Mean central macular thickness measured by optical coherence tomography decreased from 711 to 354 µm postsurgery. In conclusion, short-term mPVR is a different entity from macular pucker in terms of rapid development, structural distortion, and visual compromise. Surgical treatment significantly restores macular function and anatomy.

RESUMO

AIM: To analyze the risk factors, ophthalmological features, treatment modalities and their effect on the visual outcome in patients with endogenous fungal endophthalmitis (EFE). METHODS: Data retrieved from the medical files included age at presentation to the uveitis clinic, gender, ocular symptoms and their duration before presentation, history of fever, eye affected, anatomical diagnosis and laboratory evidence of fungal infection. Medical therapy recorded included systemic antifungal therapy and its duration, use of intravitreal antifungal agents and use of oral/intravitreal steroids. Surgical procedures and the data of ophthalmologic examination at presentation and at last follow-up were also collected. RESULTS: Included were 13 patients (20 eyes, mean age 58y). Ten patients presented after gastrointestinal or urological interventions and two presented after organ transplantation. In one patient, there was no history of previous intervention. Diagnostic vitrectomy was performed in 16 eyes (80%) and vitreous cultures were positive in 10 of the vitrectomized eyes (62.5%). In only 4 patients (31%), blood cultures were positive. All patients received systemic antifungal therapy. Sixteen eyes (80%) received intravitreal antifungal agent with voriconazole being the most commonly used. Visual acuity (VA) improved from 0.9±0.9 at initial exam to 0.5±0.8 logMAR at last follow-up (P=0.03). A trend of greater visual improvement was noted in favor of eyes treated with oral steroids (±intravitreal dexamethasone) than eyes that were not treated with steroids. The most common complication was maculopathy. Twelve eyes (60%) showed no ocular complications. CONCLUSION: High index of suspicion in patients with inciting risk factors is essential because of the low yield of blood cultures and the good general condition of patients at presentation. Visual prognosis is improved with the prompt institution of systemic and intravitreal pharmacotherapy and the immediate surgical intervention. Oral±local steroids could be considered in cases of prolonged or marked inflammatory responses in order to hasten control of inflammation and limit ocular complications.

RESUMO

The poor natural history of central retinal artery occlusion (CRAO) is usually not modified with conventional, conservative management techniques. Guidelines for selective intraarterial ophthalmic thrombolysis are still lacking. While many centers continue to perform this procedure with promising results, others are reluctant due to conflicting findings in recent studies. We present our experience in a 36-year-old male with CRAO. Based on the patient's clinical presentation, we planned to perform selective intraarterial ophthalmic thrombolysis via the ophthalmic artery. When angiography demonstrated that the retina was not supplied by the ophthalmic artery, but by a meningo-ophthalmic artery branching from the internal maxillary artery, we instead administered thrombolytic agents via the meningo-ophthalmic artery. The patient's vision recovered completely, with visual acuity and visual field examination at 30 day follow up comparable to his pre-treatment status. This case emphasizes the need for external carotid artery examination in cases of nonvisualization of the ophthalmic artery. In addition, it illustrates the successful use of the meningo-ophthalmic artery to perform selective intraarterial thrombolysis for CRAO.

RESUMO

PURPOSE: To demonstrate a sub-type of idiopathic inner lamellar macular hole (ILH) that may merit surgical consideration. METHODS: The study was conducted on patients examined with optical coherence tomography (OCT) between August 2001 and December 2003 and included 22 patients each with ILH in one eye. Eyes with persistent vitreofoveal adherence at the ILH site were included in the study. Eyes that had previously undergone posterior vitrectomy and removal of the posterior hyaloid were excluded. RESULTS: Out of the 22 cases, persistent vitreous adherence to the edge of the ILH was detected in 3 eyes (3 patients; 13.6%). The ILH occurred spontaneously in 2 eyes and was detected after extraction of an intraocular foreign body in one eye. The vitreous adherence at the ILH, related to the incompletely detached posterior hyaloid in each, was asymmetric: in 2 eyes it was detached only nasal to the ILHs; in the third eye the posterior hyaloid was detached for 360 degrees around the adherence site, but appeared much thicker at a specific site than elsewhere. CONCLUSIONS: The findings indicate that persistent vitreofoveal adherence might be present in eyes with ILH. Further studies should signify whether such ILHs have a potential of progression, cases in which surgical intervention should be considered.

RESUMO

PURPOSE: To compare retinal detachment as a result of open and closed globe trauma in a pediatric age group. DESIGN: Retrospective, comparative, consecutive, interventional case series study. SETTING: Tertiary referral medical center. PATIENTS AND METHODS: One-hundred thirty-eight (5.7%) of 2,408 retinal detachments that were treated at our facility between 1980 and 2000 occurred in children aged 18 years or younger. Of these, 37 eyes (26%, n = 36) had retinal detachment following open globe injury and 23 eyes (14%, n = 20) had retinal detachment following closed globe injury. Those were compared with regard to the retinal detachment characteristics, number, types and timing of surgeries, and the anatomic and functional surgical outcome. RESULTS: Similar incidence was found in the type of retinal detachment, number of tears, extent, macular attachment type, and timing of surgery. Anatomic surgical success was achieved in 16 eyes (46%) with open globe injury and in 13 eyes (65%) with closed globe injury. The improvement in visual acuity was limited and comparable in both groups (23% to 25%), and lower than the expected according to the Ocular Trauma Score (OTS). The only predictor for favorable visual outcome of > or =20/200 was preoperative macular attachment (P =.003, Fisher exact test). CONCLUSION: The type, extent, and severity of the retinal detachment were similar in both open and closed globe injuries, suggesting that the detachment is caused by secondary indirect impact of globe deformation. The anatomic and functional surgical outcome was guarded and similar, suggesting that further surgical innovation is required to improve the visual outcome in this age group.
