Alport Syndrome and Femtosecond Laser Assisted Cataract Surgery

We report the surgical management of a patient with bilateral anterior lenticonus due to Alport syndrome using femtosecond laser-assisted cataract surgery (FLACS) and the Optiwave Refractive Analysis (ORA) system. A 38-year-old man with Alport syndrome presented to our department with visual loss due to anterior lenticonus in both eyes. Adjustments during bilateral FLACS were performed with the software’s calipers to manually delineate the anterior capsulotomy. Multifocal toric intraocular lenses (IOLs) were selected and placed in the posterior chamber with the aid of intraoperative aberrometry. The intended postoperative positioning parameters for the IOL as well as the planned visual acuity and refraction were achieved. The implementation of FLACS and intraoperative wavefront aberrometry is a safe and useful surgical approach for the management of cataract in challenging cases such as patients with anterior lenticonus due to Alport syndrome.

Multiple Vitelliform Lesions as a Retinal Manifestation of Alport Syndrome

Alport syndrome is associated with various ocular phenotypic features, including several retinal manifestations. The purpose of this case report was to describe a case of multiple vitelliform lesions in Alport syndrome. This particular finding has, to our knowledge, not been reported previously. A 63-year-old man with known Alport syndrome presented with symptomatic, bilateral anterior lenticonus. Fundoscopic examination revealed multiple vitelliform lesions, which were symmetrically distributed at the posterior poles. Additional retinal findings included an irregular foveal contour and central macular thinning in both eyes, as well as a multilayered retinoschisis in the left eye. The underlying pathophysiology of the vitelliform lesions may be a dysfunctional Bruch’s membrane.

Alport syndrome with bilateral simultaneous anterior and posterior lenticonus with severe temporal macular thinning

Alport syndrome (AS) is a hereditary disease with various modes of inheritance, X-linked being the the most common. Anterior lenticonus is the characteristic abnormality along with perimacular and peripheral fleck retinopathy. Our two cases of AS had simultaneous anterior and posterior lenticonus with severe temporal macular thinning on optical coherence tomography with no specific renal symptomatology and were diagnosed as AS without any invasive renal biopsy. First patient was a 19-year-old man who presented with compound myopia due to bilateral anterior and posterior lenticonus with perimacular fleck retinopathy and lozenge sign and bilateral moderate sensorineural hearing loss (SNHL). Second patient was a 24-year-old man who presented with difficulty in vision due to bilateral anterior and posterior lenticonus with bilateral severe SNHL. Our cases emphasise the crucial role of an ophthalmologist in diagnosing AS before the onset of renal symptoms and prompting further nephrological work-up in the patient or the carrier.
