Dorzolamide-Induced Choroidal Detachment In A Surgically Untreated Eye

Goldberg S, Gallily R, Bishara S, Blumenthal EZ. Am J Ophthalmol. 2004 Aug;138(2):285-6. Department of Ophthalmology, Hadassah-Hebrew University Medical Center, Jerusalem, Israel. ABSTRACT: PURPOSE: Choroidal detachment is a known complication of topical hypotensive agents when used to treat eyes sensitized by prior surgery. We document the abrupt development of an extensive choroidal detachment after initiation […]

A Presumed Reflex By Which Upward Gaze Induces Relaxation Of Accommodation, A Way To Overcome Instrument Myopia

Blumenthal EZ. Med Hypotheses. 1991 Dec;36(4):381-3. ABSTRACT: This hypothesized reflex relates the vertical direction of gaze to the amount of tension exerted by the ciliary muscle. Based on simple observations the following is assumed. When looking downwards a tendency for closer focusing (near searching) exists even without a specific visual stimulus, whereas looking up favors

Could Cancer Be A Physiological Phenomenon Rather Than A Pathological Misfortune?

Blumenthal EZ. Med Hypotheses. 1992 Sep;39(1):41-8. Comment in: Med Hypotheses. 1995 Apr;44(4):306. Hadassah Medical Center, Hebrew University, Jerusalem, Israel. ABSTRACT: The hypothesis presented here is that cancer is not a phenomenon where the normal functions of the human body break down (like diabetes mellitus or renal failure) but rather a well planned and well coordinated

On The Origin Of Cancer

Blumenthal EZ. Med Hypotheses. 1996 Jun;46(6):581-3. Comment in: Med Hypotheses. 1997 Nov;49(5):447-8. Hadassah University Hospital, Jerusalem, Israel. ABSTRACT: In this paper, I present a highly unorthodox and provocative hypothesis, namely that cancer is an evolutionarily derived phenomenon, dormant in every human cell and actively triggered in certain individuals. Cancer is shown to help maintain the

A Gliacentric View Of The Human Retina

Sisak I, Blumenthal EZ. Oftalmologia. 1996 Jan-Mar;40(1):26-8. Department of Ophthalmology, Brasov County Hospital, Romania. ABSTRACT: The structure of retina was historically described using light microscopy histological sections. This description placed prime importance on neural elements and their interconnections is establishing retinal structure. Of the 10 retinal layers, 7 are neural elements. This neurocentric description is,

The Relative Distribution Of Retinal And Choroidal Blood In The Human Retina

Sisak I, Blumenthal EZ. Oftalmologia. 1996 Jan-Mar;40(1):45-7. Department of Ophthalmology, Brasov County Hospital, Romania. ABSTRACT: In this paper a model is presented to explain the relative distribution of retinal and choroidal blood to the human retina. According to this model the retina between the inner limiting membrane and the outer limiting membrane is metabolically controlled

Assessment Of The Retinal Nerve Fiber Layer In Clinical Trials Of Glaucoma Neuroprotection

Blumenthal EZ, Weinreb RN. Surv Ophthalmol. 2001 May;45 Suppl 3:S305-12; discussion S332-4. Glaucoma Center, University of California-San Diego, La Jolla, CA 92093-0946, USA. ABSTRACT: Assessment of the retinal nerve fiber layer (RNFL) is appealing for use in clinical trials of glaucoma neuroprotection, as it is directly correlated with loss of ganglion cells, which is assumed

Steroid Induced Glaucoma (Article In Hebrew)

Sapir-Pichhadze R, Blumenthal EZ. Harefuah. 2003 Feb;142(2):137-40, 157. Department of Opthalmology, Hadassah University Hospital, Jerusalem, Israel. ABSTRACT: Steroid treatment has gained notoriety due to its tendency to induce multiple side effects, including a variety of ocular side effects. Administration of local, regional, inhalation or systemic steroids may induce the development of ocular hypertension, which might

Bridging Analog And Digital Video In The Surgical Setting

Miron H, Blumenthal EZ J Cataract Refract Surg. 2003 Oct;29(10):1874-7. Comment in: J Cataract Refract Surg. 2004 Oct;30(10):2032-3. Department of Ophthalmology, Hadassah-Hebrew University Medical Center, Jerusalem, Israel. ABSTRACT: Editing surgical videos requires a basic understanding of key technical issues, especially when transforming from analog to digital media. These issues include an understanding of compression-decompression (eg,
