All patients were followed for a minimum of six months postoperatively. The principal outcome measures were re treatment rate, safety, efficacy in terms of
uncorrected distance visual acuity (UDVA) and uncorrected reading ability (vocational
reading test), patient satisfaction, stability and predictability. Results: 76
eyes of 38 patients were treated. 42% of patients (16 patients) that were
treated required at least one re-treatment.
Twelve children (7-13 years old) with MRNFs were included. Fourier
domain optical coherence tomography was used to image both the peripapillary
RNFL and the macular retinal structures in 6 patients. Using the instrument’s segmentation software, global RNFL thickness and central subfield thickness(CST) of the macula were analyzed. Planimetry was used to quantify the MRNF
area observed on fundus photography. Visual acuity and cycloplegic refractive
errors (spherical equivalent) were also recorded. Results from the MRNF-affected
eye were compared with the fellow eye.
Endophthalmitis is a severe
inflammation of the inner eye's structures, caused by an exogenous or
endogenous infection with microorganisms which can multiply rapidly. It occurs most frequently after intraocular surgery. Moreover, it can also be a
consequence of a penetrant eye injury or a hematogenous dissemination of
microorganisms. The most common pathogens of this inflammation are bacteria,
next to fungi and less frequently parasites.
The occurrence, severity and
clinical presentation of endophthalmitis depend on the way of infection, the
number and virulence of pathogenic bacteria, as well as the patient's immunity
state. The type of endophthalmitis can suggest the possible causative agent.
Furthermore, it can help determine therapeutic approach or antibiotics to
choose. The more virulent are the causative agents, the early the symptoms and
signs of endophthalmitis appear.
Epidermal cysts are benign slow
growing tumors resulting from proliferation of epidermal cells. Usually cysts
are asymptomatic; however, they may become inflamed or secondarily infected.
Epidermal cysts are solitary sub epithelial cysts, are slowly progressive and firm in consistency. They are most commonly seen on the face, scalp, neck and
trunk. Epidermoid cysts are frequently seen on the upper eyelid, mainly on the
conjunctiva or on the skin. This may be misdiagnosed as chalazion or sebaceous
cyst. Surgical excision of the cyst in toto is the treatment of choice or else
there will be recurrence, granulomatous reaction or foreign body reaction.
They were divided into two sets;
forty nine right eyes were kept at 32°C while forty nine right eyes were kept
at 4°C in a mobile refrigerator. The samples of vitreous were carefully aspirated from the bovine eyes within an hour of death of the animals.
Measurements of the levels of cations (sodium and potassium) and anions
(chloride and bicarbonate) were taken at various postmortem intervals of 2, 12,
24, 36, 48, 60 and 72 hours, using E110111 Flame Photometer.
Myelinated
retinal nerve fibers (MRNFs) are developmental anomalies of the retina that
appear as white to grey-white striated patches with feathery edges, often
distributed around or contiguous with the optic disc and surrounding the
vascular arcades. Based on a fundus photography study including 5789 patients,
Kodama et al. reported that MRNFs occur in approximately 0.57% of the
population, most often involving superior and inferior-temporal per papillary
areas. No MRNFs were discovered in the macula, and 7.7% were bilateral.
Concomitant
intraocular and orbital space-occupied lesions are relatively rare and this is
the first report stressing the underlying causes of concomitant intraocular and
intra orbital lesions. In this paper, we present cases showing both intra ocular and orbital soft tissue masses and highlight their clinical, pathological and
imaging features. In clinical practice supplementary space-occupied disorders
that might involve both intraocular and orbital tissues require consideration.
To answer this question: I
certainly hope not, at least not always. Without a doubt over the past several
years the contact lens industry has brought forth numerous new materials,
designs, and modes of contact lens manufacturing. But that should not translate into a universal switch from the “old” to the “new”. I would like to share some
specific instances where older lens materials and designs should still have a
place in your practice.
Although without a question newer
more oxygen permeable rigid gas permeable (RGP) materials have been key to the
introduction of such modalities as overnight wear of Ortho keratology lenses,
these materials often have some less advantageous attributes. Although we often only consider oxygen permeability (Dk) and lens wettability when selecting a RGP material, one should also consider that such materials often have lower
material hardness and greater modulus.
