Peripapillary Hyperreflective Ovoid Mass-Like Structures in Stickler Syndrome.

PURPOSE: To report a previously undescribed finding of peripapillary hyperreflective ovoid mass-like structures (PHOMS) in Stickler syndrome. DESIGN: Noncomparative case series. SUBJECTS: Twenty-two eyes with anomalous optic disc from 11 Stickler syndrome patients were identified and imaged. METHODS: Peripapillary hyperreflective ovoid mass-like structures were graded using enhanced-depth imaging OCT (EDI-OCT) according to the consensus recommendations of the Optic Disc Drusen Studies Consortium. All EDI-OCT scans were obtained using the Heidelberg Spectralis (Heidelberg Engineering) with a dense horizontal raster (15 × 10°, 97 sections) centered on the optic nerve head and graded by 2 independent assessors. In case of disagreement, the image was graded by a third assessor. The presence of any coexisting optic disc drusen was also assessed using EDI-OCT and autofluorescence. MAIN OUTCOME MEASURES: The presence of PHOMS, clinical characteristics and genetic mutations. RESULTS: A pilot sample of 22 eyes with phenotypic optic disc abnormalities from 11 Stickler syndrome patients were identified and imaged. Eight patients were female and 3 were male. The mean age was 31 years (13-58 years). Peripapillary hyperreflective ovoid mass-like structures were present in 91% (n = 20) of imaged eyes. Seventy percent (n = 14) were type 1 Stickler syndrome and 30% (n = 6) were type 2 Stickler syndrome. All eyes were myopic and the degree of myopia did not seem to affect whether or not PHOMS was present in this cohort. One eye with PHOMS had retinal detachment, and 77.3% (n = 17) of eyes had undergone 360o prophylactic retinopexy. Thirty-two percent (n = 7) of eyes with PHOMS were present in patients with coexisting hearing loss and 22.7% (n = 5) had orofacial manifestation of Stickler syndrome in the form of a cleft palate. Seventy-seven percent (n = 15) of eyes with PHOMS were present in patients who reported joint laxity or symptoms of arthritis. No coexisting optic disc drusen were identified and raised intracranial pressure was also excluded after neurological investigation. CONCLUSIONS: These data suggest that PHOMS are a novel finding in Stickler syndrome patients and should be considered when evaluating the optic nerves of these patients.

RHEGMATOGENOUS RETINAL DETACHMENT AFTER INJECTION OF TISSUE PLASMINOGEN ACTIVATOR AND GAS FOR SUBMACULAR HEMORRHAGE SECONDARY TO AGE-RELATED MACULAR DEGENERATION.

PURPOSE: The purpose of this study was to describe the rate, clinical characteristics, and outcomes of rhegmatogenous retinal detachment (RRD) after injection of tissue plasminogen activator (TPA) and gas for submacular hemorrhage displacement. METHODS: Retrospective analysis of consecutive cases developing RRD after TPA injection and gas for submacular hemorrhage displacement. The rate of RRD was calculated, and a description of RRD clinical characteristics was performed. Anatomic and visual outcomes after RRD repair were analyzed. RESULTS: Ninety eyes of 90 patients were analyzed. Tissue plasminogen activator was given intravitreally in 53 eyes (59%) and subretinally in 37 eyes (41%). RRD occurred in 6 of 90 eyes (7%). Of these, one had intravitreal TPA and five had vitrectomy with subretinal TPA ( P = 0.04). The mean age was 75 (64-93) years. The median time of RRD occurrence was 42 (1-134) days. All cases had macular involvement. Two cases had PVR at presentation. Vitrectomy was performed in all cases and silicone oil used in five, all of which resulted in permanent silicone oil retention. One case (17%) achieved primary single surgery success. The median final visual acuity was 1.8 logMAR (20/1,260 Snellen). CONCLUSION: The RRD rate after submacular hemorrhage displacement was 7% in our case series. Rhegmatogenous retinal detachment occurred more commonly after vitrectomy with subretinal TPA injection. The visual and anatomic outcomes were poor, with a high rate of retained silicone oil and recurrent RRD.

Surgical Management of Intraocular Silicone Oil Microdroplet.

PURPOSE: Intraocular silicone oil microdroplets have been described after intravitreal injection of anti-VEGF agents packaged at a compound pharmacy. We present a case with the presence of an intraocular silicone oil microdroplet after a vitreoretinal operation using disposable instruments, and the surgical technique for its removal. METHODS: A 59-year-old patient who had been operated on for vitreous opacities using a disposable 27-g vitrectomy kit complained of a small round structure floating in the eye. It appeared a few days after surgery. The bubble was not present at all times and it disappeared for days on end. Clinical examination of the vitreous and retina during these uneventful periods was normal. The bubble reappeared intermittently without a link to any specific movement for some time but was again absent once the patient was examined. The physical properties of the mobile round lesion could be identified as lighter than aqueous humor, as it was described as being in the center of the visual field if the head was tilted forward. RESULTS: As the patient was very bothered by this bubble, a 23-g vitrectomy was performed. During deep indentation of the pars plana over 360 degrees, a tiny bubble of silicone oil could be found buried in the peripheral vitreous base, and controlled aspiration under deep indentation was performed. The patient has been without symptoms since the removal of the droplet and made an uneventful clinical recovery. CONCLUSION: Microdroplets of silicone oil may be present in disposable vitreoretinal instruments and stay in the eye after surgery, causing a visual disturbance. The origin of these droplets may be linked to the plastic tubing of the instruments.

Corneal Scarring and Hyperopic Shift After Corneal Cross-linking for Corneal Ectasia After SMILE.

PURPOSE: To report a case of severe corneal scarring and hyperopic shift after corneal cross-linking (CXL) for the treatment of ectasia following small incision lenticule extraction (SMILE). METHODS: Case report and literature review. RESULTS: A 35-year-old man was referred with severe unilateral corneal haze that developed after CXL. The patient had undergone SMILE 4 years earlier in both eyes. Nineteen months postoperatively, the patient presented with bilateral decrease in vision and corneal topography revealed corneal ectasia in the right eye. CXL was performed in the right eye and a deep stromal haze was observed 1 year later. Comparative maps showed progressive corneal thinning with corresponding flattening that induced hypermetropization and astigmatism. CONCLUSIONS: CXL after SMILE in this original case resulted in severe deep corneal haze and corneal flattening with hyperopic shift. [J Refract Surg. 2018;34(11):779-782.].

Frozen section in laparoscopic management of macroscopically suspicious ovarian masses.

STUDY OBJECTIVE: To study the usefulness of and applications for frozen section in the laparoscopic management of adnexal masses. DESIGN: Historical prospective study (Canadian Task Force classification II-3). SETTING: Large tertiary care hospital with university affiliation. PATIENTS: One hundred forty-one women undergoing laparoscopy for a suspicious adnexal mass. INTERVENTION: Adnexal masses suspicious on ultrasound were managed by laparoscopy. After laparoscopic diagnosis, frozen sections were used to confirm a diagnosis of malignancy. Treatment was performed by laparoscopy whenever feasible. MEASUREMENTS AND MAIN RESULTS: The results of frozen section were compared with the results of permanent sections, and the consequences of the intraoperative diagnosis on the surgical management were evaluated. The frozen section diagnosis was correct in 125 of the 141 patients (88.7%). In one patient, the result was false negative. Specifically, frozen section diagnosis was correct in 96.8% of cases when a cyst or biopsy was sent for pathologic examination and in 86.4% when the whole adnexa was sent. It was correct in 93% of the cases involving tumors smaller than 100 mm and in 74% of larger tumors. It was correct in 92.3% of the women younger than 50 years and in 81.6% of women older than age 50. Intraoperative pathologic diagnosis was correct in 95.5% of benign tumors, 77.8% of low-malignancy tumors, and 75% of cancer cases. CONCLUSION: Frozen section is a useful examination for surgical management decision making; however, the limitations and the difficulties should be taken into account.

Laparoscopic management of adnexal masses: a gold standard?

PURPOSE OF REVIEW: To review recent literature on the laparoscopic management of adnexal masses, when this approach may be considered as a gold standard. RECENT FINDINGS: Cyst rupture was recently demonstrated to be a significant prognostic factor in stage I invasive epithelial carcinoma, and it was recommended to restrict the laparoscopic approach to patients with preoperative evidence that the cyst was benign. The laparoscopic approach is still highly controversial in masses suspicious at ultrasound. The limits of the laparoscopic approach are discussed reviewing recent literature and our experience. The laparoscopic management of adnexal masses appears to be safe in most hospitals even in developing countries. This approach is being used with increasing frequency in unusual indications such as newborns, children, adolescents and pregnant women. The learning curve for endoscopic surgery appears to be longer than expected. Many patients with benign adnexal masses, such as ovarian endometrioma, are still treated by laparotomy or with an inadequate endoscopic technique. Several studies have suggested that the stripping technique is a tissue-sparing procedure. SUMMARY: The laparoscopic puncture of malignant ovarian tumours confined to the ovaries is uncommon, and should be avoided whenever possible. The teaching of endoscopy is essential to promote adequate procedures performed according to the principles of microsurgery and to preserve postoperative ovarian physiology.
