SPONTANEOUS CLOSURE OF SIMULTANEOUS IDIOPATHIC MACULAR HOLES DOCUMENTED BY SPECTRAL-DOMAIN OPTICAL COHERENCE TOMOGRAPHY.

PURPOSE: To report a case of spontaneous closure of simultaneous full-thickness macular hole. METHODS: Case report and literature review. RESULTS: A 67-year-old woman with small-diameter simultaneous macular holes was observed for a period of 5 months, and progression was documented with spectral-domain optical coherence tomography. Closure of right full-thickness macular hole was evidenced by 1 month and left full-thickness macular hole by 5 months. CONCLUSION: This case demonstrates possible spontaneous resolution of a condition that is usually treated surgically. A period of observation with serial imaging studies may be advised in cases of small macular holes.

Eighty-micron flap femtosecond-assisted LASIK for the correction of myopia and myopic astigmatism.

PURPOSE: To evaluate the safety and efficacy of 80-µm flap femtosecond laser-assisted LASIK and the early clinical and refractive outcomes in the correction of myopia and myopic astigmatism. SETTING: Private practice, outpatient. DESIGN: Prospective study. METHODS: Patients who underwent femtosecond-assisted LASIK between February and April 2018 were included. Inclusion criteria were myopia from -1.00 to -8.00 diopters (D) and astigmatism up to -3.00 D and no previous surgeries. All patients were tested preoperatively and on day 1 and month 3 for uncorrected distance visual acuity (UDVA), manifest refraction, corrected distance visual acuity (CDVA), intraocular pressure (IOP), slitlamp and dilated fundus examination, Schirmer I test with anesthesia, and ocular surface disease index questionnaire. The FEMTO LDV Z8 was used for flap construction and the Wavelight Allegretto 400 excimer for refractive treatment. Flap thickness was measured at week 1 with anterior segment optical coherence tomography (AS-OCT). RESULTS: Eighty-two eyes were included. Logarithm of the minimum angle of resolution UDVA was 1.28 ± 0.53 preoperatively, 0.02 ± 0.05 at day 1, and 0.14 ± 0.127 at month 3. There was no loss of CDVA lines. The mean flap thickness measured at 1 week with AS-OCT was 73 ± 6.7 µm. CONCLUSIONS: The use of ultrathin flaps, just below Bowman's layer, with the Ziemer LDV Z8 femtosecond laser was possible, safe, reliable, and reproducible. Eighty-micron flaps allowed for excellent vision on 1 day post-LASIK and might be a good alternative to maintain an appropriate percentage of tissue altered, especially when attempting greater corrections or larger treatment zones.

Anatomical Changes of Full-Thickness Macular Hole Documented by Microscope-Integrated Spectral-Domain Optical Coherence Tomography.

BACKGROUND AND OBJECTIVE: To evaluate anatomical changes of idiopathic macular hole (MH) after internal limiting membrane removal and after passive suction at the hole's borders using microscope-integrated intraoperative optical coherence tomography (iOCT). PATIENTS AND METHODS: Five eyes of five subjects with full-thickness idiopathic MH underwent phacoemulsification, intraocular lens implantation, pars plana vitrectomy, and internal limiting membrane (ILM) removal. iOCT was performed after ILM removal and after passive suction at the hole's borders. RESULTS: iOCT showed decreased MH diameter after ILM removal in all cases. Passive suction achieved complete apposition of borders. All cases presented successful postsurgical closure. CONCLUSIONS: iOCT provides anatomical information during MH surgery that may impact surgical decision-making by allowing a real-time evaluation of structures. iOCT with preservative-free triamcinolone acetonide enhanced ILM visualization. Its use is superior to iOCT alone for the identification of vitreomacular interface structures. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:e105-e111.].

Minimally Invasive Surgery for the Removal of Posterior Intraocular Foreign Bodies.

This is a prospective clinical assay that included six patients who were diagnosed with penetrating corneal injury, traumatic cataract, and posterior segment intraocular foreign body (IOFB). Following anterior segment repair and extraction of traumatic cataract by clear cornea phacoemulsification, a standard 25-gauge transconjunctival pars plana vitrectomy was performed to find and release the IOFB. With active suction using a 25-gauge silicone tipped cannula, the foreign body was retrieved and safely placed in the anterior chamber. After stabilization of the anterior chamber with viscoelastic injection, IOFB extraction through the main phaco incision was easily performed, followed by placement of an intraocular lens. Of the six patients, 66.6% showed a significant improvement of visual acuity. No complications associated directly with the surgical procedure occurred. Our surgical technique is a safe alternative for handling and removing a posterior IOFB. There was no need for a scleral incision.
